Harry sat back on his seat, and what had just happened made him think he hadn't woken up, or had had April Fool's Day in advance. But the twins and Wood had already surrounded him, and they also saw Professor McGonagall's serious face and heard the argument between them.

Although they didn't hear everything clearly, the "Qidditch" that came occasionally made them frightened.

Harry explained the trouble he encountered. Although Wood looked bad, he comforted him, "It doesn't matter. You come back before dark, let's continue training. Anyway, your positioning is a free man, and the impact is not great..."

He finally made a bad joke, "Blake wouldn't have been imprisoned for more than ten years, his eyes are bad, so he recognized me as you?"

The twins laughed heartlessly, and it was not easy to recognize the burly Wood as Harry.

But Harry was not in the mood to laugh. He realized that Black, the fugitive who had been in prison for twelve years, was once so close to him.

"Perhaps, I should spend more of my thoughts on the papers in the duel system." Harry touched his schoolbag, where the beginning of a paper was hidden.

On weekends, as Halloween approaches, the festive atmosphere becomes stronger and stronger.

Felix got up early and looked at the paper in his hand.

‘…The above explanation, we may have found a new treatment for memory damage, which will be more targeted than old drugs and curse treatments. The only problem is that we need to find a way to stably connect patients’ memory, not a short and malicious snooping of thoughts like the God-taking thoughts, but a way to communicate information in a cooperative state.

At the same time, for examples of extreme memory damage (large-area permanent damage, memory breakdown), simple bonding cannot cope with this situation. We need to consider giving memory a stable structure...'

Felix nodded with satisfaction, "The whole paper is theoretical deduction, but it also vaguely mentions the most critical part - the magic of the hut of thinking and the structure of solid memory."

"First throw it out and see the reaction, um... I can post it in the monthly magazine of "Prophet Daily". It has some influence, but its professionalism is not appropriate, and the brewing cycle is longer."

"I guess it will not spread in the therapist group until mid-to-late November. Things like this purely theoretical will definitely attract different opinions. At that time, the situation of the Longbottom couple may not be hidden, but I can just use this as an excuse to avoid the intervention of St. Mungo at a higher level. No one will be stupid enough to reject a potential Knights of Merlin."

He put away the paper, just adjust the wording, copy it again, and then it can be sent out.

Felix sat on the sofa, thinking about how to simplify the treatment plan. This was also the advice Dumbledore gave him. Whether it was the magic of the Thinking House or the memory nodes inherited from Ms. Ravenclaw, they were extremely valuable knowledge. He was not so energetic and he could publish it casually.

What's more, few people can learn it.

"The simplification of the magic of the Thinking House is relatively easy, and I know it well. As for the memory node..." Felix thought for a while, and decided to throw out the structure of stable memory that he had secondly understood from Ms. Ravenclaw's inheritance - this is what he applied to magic puppets, which allows them to have relatively stable personalities and habits, and even rehearse dramas by themselves.

In the glass container on the workbench, the eight-eyed giant spider urged in a hoarse voice: "Hurry up, hurry up! I can't wait."

Felix turned around: "I really don't think about it anymore? I can give you a holiday and plenty of food..."

"Stop talking, stop talking!" said the eight-eyed giant spider irritably, "Let me go back."

"Okay." Felix reached out and grabbed it. The glass container on the workbench flew into his hand. With a "click", the size of the eight-eyed giant spider continued to shrink and soon became as big as the fingertips of the thumb.

Felix put it back into a small-mouthed glass bottle, and a small sound came from the bottle, "Your magic has improved again, I don't feel anything unusual, maybe, I mean maybe... occasionally cope with your test." Felix curled the corner of his mouth and stuffed the bottle into his pocket.

He glanced at the time and appeared at the entrance of the castle at the pinch point. After two minutes, when he thought he could not wait for someone, Luna jumped and appeared.

"Felix, I prepared some buttered peas, Ferrenze would like it." She said, pointing to the woven flower basket.

Felix didn't know the taste of the horseman, but he didn't like the taste very much, so he changed the subject and said, "Let's go, let's meet your friends."

They went down the slope, passing through the greenhouse and the beaten willow, and the Hagrid House appeared far away from sight, but they did not get close, but turned a corner and penetrated straight into the forbidden forest.

After passing through a barrier of trees, they soon arrived at a clearing. The clearing was covered with moss and various wild flowers, and several stones were carefully cleaned up. It was obvious that this was Luna's secret base.

Luna took out a whistle from her pocket, bloated her cheeks and blew it up. The sound was not loud, and it perfectly integrated into the "rustling" wind around. Felix judged that this was a magic item.

Soon, Felix heard the sound of horse hooves trotting, and a young horseman appeared, with white hair and a silver-maned horse body.

The reason why Felix judged him to be "young" was seen from his human face. The horseman carefully looked at him through the branches and leaves of the trees, and half of his body was hidden behind the trunk.

"Little Luna, is he your teacher?" asked the horse man. Felix was wearing exquisite clothes, which made him not doubt Felix's identity as a professor.

"Yes, come on, I have prepared new food for you, let's try it together!" Luna said happily.

Ferenze came out from behind the trunk and stopped two meters away from Felix. He froze his face, "Hello, I'm Ferenze."

"Oh, hello, I'm Felix Happ." Felix said politely.

"Listen, wizards. We usually don't deal with people, especially adult wizards. If it weren't for Little Luna letting me meet you..."

Felix smiled and said, "I know the horses are xenophobic, but I think you will be an exception. And I came here to discuss with you because of some serious issues."

Ferenze stared and said, "What's the problem?"

"Do you know Sirius Black?"

"I've heard of this name and it's a dangerous person." Ferenze said casually.

"Yes, he escaped from Azkaban, and the Ministry of Magic and the Dementors were so angry. By the way, have you ever seen the Dementors?"

Ferenze said stiffly: "I don't, but some tribe members said they had seen their shadows."

"That's it," Felix said. "Forbidden Forest is not safe, and IMHO, if the dementors are really out of control, I don't think you'll have any good ways to fight them."

The horseman digged the soil with his hooves, and his face showed an angry expression, but he knew that this sentence was true.

Felix continued: "It's too dangerous to get a student close to the Forbidden Forest, and it's a violation of school rules. My opinion is to be cautious before the Dementors are withdrawn."

"You want to stop us from meeting?"

"I had no intention of destroying a friendship. When Luna grew up, it might be a wonderful memory. Ferenze, should you and Hager know each other?"

"Know." said the horse man.

Felix laughed, "Isn't that great? I don't think Hagrid would mind receiving you, maybe it's nice to meet in the pumpkin field behind Hagrid's cottage."

"Hagir may be stronger than the Horseman, but I don't think he can deal with the Dementors."

Felix shook his head, "Ferenze, you still don't understand that Hagrid is a wizard. No matter how he usually acts, there is no doubt that he is a wizard, and his methods are more than you and your tribe combined."

"Maybe he can't fight Dementors, but it's okay to persist for a short period of time until they get support. What's more, what we're talking about is the most extreme situation, and examples of dementors losing control are relatively rare."

Ferrenze reluctantly agreed, and he walked forward, bent down and shook hands with Felix.

"You can see that you have no prejudice against the horses, Mr. Happ," he said.

"Oh, of course not, Ferenze, do you know where the Eight-Eyed Giant Spider's nest is?" Felix asked.

"Know," Ferenze pointed in a direction hesitantly, "their nests are on the west side of the tribe. Many years ago, we fought one, and their hunting range will not cross the boundaries we drew."

Felix roughly speculated about the location of the horsemen's settlement, spider nest and Hogwarts. He suddenly discovered that the horsemen separated the eight-eyed giant spider group. Even if the little wizard was playful, it would be difficult for the rugged road for several hours, and it was very likely that he was discovered by the horsemen and expelled back.

In the next time, except for Luna in a good mood, Felix and Felix didn't talk much. Felix and Luna shared "morning tea", that is, the plate of butter peas. Luna also wanted Felix to taste it, but he directly refused.

Before leaving, Ferenze hesitated, "Maybe you are right."

"What?" Felix asked.

"The danger is approaching..." The horse man shook his silver tail a little uneasy, "The tribe members also observed that the undercurrent was surging and the darkness was approaching."

Felix laughed, "Maybe this indicates that some disappeared Dark Lord appeared again?"

Ferenze stared at him in surprise and said slowly: "I did not predict so accurately. The horseman observed the astrological signs and found some important revelations from them, but they only responded in a general way."

Felix said easily: "I can't predict, but I know more than ordinary people. When you have enough information, you can naturally see further. This is also the principle of arithmetic divination."

Come out of the forbidden forest, Luna said thoughtfully: "Are you discussing the mysterious man? Is he coming back?"

"There is this possibility." Felix did not explain in detail, she was only in the second grade.

After seeing Luna off, Felix turned around and returned to the Forbidden Forest, walked along the direction pointed by the horseman for more than ten minutes. Later, he simply used a broom to quickly pass by the low altitude.
